What about people not running one at all and just running breathers? Seems to be one of the things alot of people to do eliminate the oil coating of the intake tract.
I understand the vacum and all that, I do believe that a vacum pump in most situations will halp make power, but does the pcv with a small orifice really draw enough vacum to actually help anything?

Not to be a pain but if there is one I want it because I am filling my catch can in 20 min trac sessions. I do not think I am burning much, but two things are happening:
- Oil is building up in the valve covers (if I run fill tube a breather it pukes and runs down to headers)
- I am sucking oil from valley, thru catch can on it's way to Intake. This is nothing new as all LS engines do this to some degree depending on use. The new one is moving more air and therefore more oil I suppose, dispite gen 4 valley cover.
current confiuration on 402 LS2 ^
Factory plug on driver side rear, I think this is an 03 patch part. V

The PCV valve should be in the line from the valley cover to the intake, and has what looks like a ground strap attached to it. This is actually something to transfer heat to the PCV valve so that it unfreezes in cold weather. I've never heard of a PCV valve in the rear before, but the LS1s used to have a pipe running from back there to the PCV valve up front by the intake.

On a LS2?

This fitting has a small orifice in it and the cover has a baffle on the underside with another small orifice to keep it from sucking oil. You would have to "T" into another vacuum line off of the throttle body to hook it up.
